Question

The success of mammals on earth is largely because:

• A. They can conform to the changes in the environment.
• B. They can reduce metabolic activity and go into state of dormancy during unfavourable conditions in the environment.
• C. They have the ability to maintain constant body temperature.
• D. They can take care of their young ones as they have mammary glands to suckle them.

Answer 1

The correct option is C They have the ability to maintain constant body temperature.

• Almost all organisms can conform to changes in the environment commonly known as adaptation.
• Not only mammals but other groups also undergo hibernation.
• Young ones are fed with milk only for short period of their time so it necessarily doesn't contribute in the survival or success of an organism.
• Ability of temperature homeostasis is the biggest reason for the success of mammals as it helps them survive all kinds if external harsh conditions.
• So the correct answer is option C.
